A TTORNEYS Patented Apr. 26, 1932 UNITED STATES PATENT OFFICE EARL C. HERVEY, OF INDIANAPOLIS, INDIANA, ASSIGNOR T HYDRAULIC PRESS BRICK COMPANY, 01 INDIANAPOLIS, INDIANA, A CORPORATION OF MISSOURI APLPARATUS FOR PRODUCING ROUGH IEAOED ORNAMEN'IAL BRICK Application filed December 22, 1930. Serial No. 504,088.

The object of my invention is to produce mechanism by means of Which a new ornamental brick, which forms the subject matter of my co-pending application Serial No.

%,087 may be rapidly, eilicicntly and uniforinly produced.

The accompanying drawings illustrate my invention.

Fig. 1 is a general perspective view of a brick-forming machine capable of performing my improved method and producing the new brick;

Fig. 2 is a perspective showing portions of the forming mechanism at the point Where the novel step of my improved method is performed;

Fig. 3 is a perspective of the same portion of the mechanism shown in Fig. 2, but from another viewpoint;

Fig. 4 is a perspective of a group of the new brick, and

Fig. 5 is a perspective view, on a larger scale. of the mechanism for trimming the top and vertical faces of the issuing column, whereby the ends of the finished brick will be rough and one face will be ornamented, the pressure rolls for the vertical faces being swung outwardly so as not to obstruct view of the vertical cutter wires.

In the drawings indicates a columnforming machine of usual character capable of ejecting from its die a continuous plastic column 11. Secured to the discharge face of the machine 10 is a U-shaped' plate 12 at the middle of which is slidably mounted a de flector plate, of L-shaped cross section, 13, said plate being carried by a slotted bar 14; slidably held in place by a bolt 15 and adjustably positioned by means of a screw 16, the arrangement being such that the deflector 13 may be adjusted relative to the upper face of the issuing column 11. Extending beneath deflector 13 across the column is a cutter w re 17 passed through eyes in two hang- 5 ers 18, 18 mounted at each vertical side of the mouth of the machine 10. hangers 18 being slidably mounted on the base plate 12 by the bolt and slot mounting 19 and adjustable vertically by means of the adjusting screws 20, 20. The ends of wire 17 are anchored up on the books 21, 21 supported by base 12, one of said hooks being shiftable axially, by means of the nut 22 so that the tension of Wire 17 may be varied, the arrangement being such that that portion of wire 1( which overlies the issuing column 11, may be accurately adjusted in a plane parallel with and at the desired distance beneath the upper face of the issuing column so that it will serve to sever a uniform thin layer of material from the upper face of the issuing column. The deflector 13 is then so adjusted that the thin layer, severed by wire 17, is deflected clownwardly and forwardly over the wire and broken into relatively narrow strips having lengths substantially co-eXtensive With the widthof the column.

Arranged at each side of the issuing column are two cutter wire guides 25, 25 supporting a vertical cutter Wire 26. guide 25 is slida bly supported upon base 12 by a bolt and slot mounting 27 and is adjustable toward and from the vertical face of the column by an adjusting screw 28.

One end of each of the vertical wires 26 z is anchored upon an axially adjustable hook 29 adjustable by means of the nut 30 to vary the tension in the Wire.

Mounted at each side of the issuing column is a pressure roller 35, covered with sheeppelt or other suitable material and arranged to engage the adjacent vertical face of the issuing column after it passes the trimming wire 26. Each of these rollers is carried by a shaft 36 j ournaled in a yoke 37 swingable about a vertical axis 38 and urged inwardly so as to urge the periphery of its roller 35 into engagement with the vertical face of the column 11, by a spring 40 (Fig. 3)

The column 11, after passing through the trimming mechanism, illustrated in detail in Fig. 5, reaches an endless belt by which it is delivered to and through a transverse cutting mechanism 46 of any well-known form. Arranged above the initial end of belt 45 and across the issuing column is a cross bar 47 which is rotatably adjustable in its supports 48. Secured to bar 47 are the upper ends of one or more wire fingers 49 having L-shaped lower ends which, by rotation of Each 170 bar 47, may be adjusted into close proximity to the upper sub-surface of the issuing column. Between fingers 19 and the cutting mechanism 46 is a roller 50, conveniently faced with sheeppelt, which rests upon the upper surfaces of the fragments lying on the column.

Arranged beyond the cutting mechanism 16 and so as to rest upon the upper surfaces of the individualized bricks as they issue from the cutting mechanism, is a metal roller 51 to which oil may be continuously delivered from a container 52.

The operation is as follower The plastic column 11, issuing from the die of machine 10, is engaged by the wires 17 and 26, 26, each of said wires being so adjusted as to separate a thin layer from an adjacent face of the column. The material removed from the column by the wires 26, 26 drops away from the column and the adjacent roller 35 somewhat compacts the adjacent surface of the column, leaving therein, however, evidences of the action of the trimming wire.

The wire 17 removes a thin layer from the upper surface of the column and this thin layer, first curling upwardly, strikes the deflector 13 and is by it deflected downwardly over wire 17 and broken into slightly irregular narrow strips 55, the lengths of which are substantially co-extensive with the width of the column. These strips 55 are carried along with the column until they meet the obstruction of the wire fingers 49, which fingers act to fragmentate the strips 55 into shorter fragments 55' and to angularly displace these fragments but without discharging said fragments from the upper face of the column. The column 11 then proceeds, with the fragments 55 lying loosely and angularly displaced thereon, to and beneath the compacting roller 50 which, by reason of its weight, serves to press the fragments upon the sub-surface 11' of the column and cause them to adhere thereto and, by reason of its sheeppelt facing, retaining the somewhat loosened or wrinkled outer faces of the frag ments 55. The column 11 with its adhered fragments 55 then passes throughthe cutting mechanism 46 by which it is dimensioned into individual bricks and these individualized bricks are then carried beneath the roller 51 which glosses the upper surfaces of the fragments 55 so that, when the individualized bricks are subjected to the usual burning operation, the outer faces of the fragments 55' will be glossed as compared with the exposed portions of the subsurface of the main body of the brick to which the fragments 55 are adhered. If it is desired that the exposed faces of the fragments shall not be glossed, the roller 51 may be removed from the machine.
